D Brake Interlock Output (Not Allocated: BKIR)
External brake timing signals are output according to the settings in Pn506 (brake timing 1), Pn507
(brake command speed), and Pn508 (brake timing 2).
Note 1. The BKIR signal is not allocated by default. It is allocated by Pn50F.2.
Note 2. For details on the brake interlock function, refer to 4-5-8 Brake Interlock (All Operating
Modes).
D Warning Output (Not Allocated: WARN)
The WARN signal is turned ON in any of the following three cases:
S The Servomotor output torque (effective value) exceeds 115% of the rated torque.
S The regenerative energy exceeds the tolerance of the internal regeneration resistance.
S When external regeneration resistance is used, the regenerative energy exceeds the value set for
Pn600 (regeneration resistor capacity).
Note The WARN
signal is not allocated by default. It is allocated by Pn50F.3.
D Command Pulse Factor Enabled Output (Not Allocated: PSON)
The PSON signal turns ON when the command pulse factor has changed after the PSEL (command
pulse factor switching) input has been turned ON. After the PSEL input is turned OFF, PSON turns OFF
when the command pulse factor returns to 1.
Note 1. Refer to the information on the PSEL signal for details on timing for switching the command
pulse factor.
Note 2. When command pulse factor switching is used, set Pn218.0 (command pulse factor switching
function selection) to 1, and set the applicable factor in Pn217.
Note 3. Allocate the PSEL signal using Pn513.0.
Note 4. The PSON signal is not allocated by default. The PSON signal is allocated using Pn510.2.
